Hey all, I got a new 15" PB today, and all was going well until I opened up iTunes to check things out. Sound is only coming out of the left speaker, and when I went to the sound settings under system preferences (and selected the right speaker) nothing at all happened. Any suggestions before I have to send this thing in...? As for lines on the display, I think I have have them. They are faint, but if you look closely they are noticeable throughout the display. From an arm's distance away you can't notice anything, but still, I can see the potential problems from this.. Alright, thanks!
